Specification of Letters Patent.

Patented May 5, 1908.

Application filed September 10, 1907. Serial No. 392,230.

To all whom it may concern:

Be it known that I, J ENNIE Morn, a citizen of the United States,residing at Bristol, in the county of Day, State of South Dakota, haveinvented certain new and useful Improvements in Churns; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to new and useful improvements in churns and inits broad conception it comprises a churn of the rotating body typewhich is formed with a surrounding water jacket, the object of theinvention being to provide a novel construction, combination andarrangement of parts.

The details of construction will appear in the course of the followingdescription in which reference is had to the accompanying drawings,forming a part of this specification, like characters of referencedesignating similar parts, throughout the several views, wherein:

Figure 1 is an elevation of a churn constructed in accordance with thepresent invention. Fig. 2 is an elevation looking at the side of theframe of such churn. Fig. 3 is a sectional-view taken vertically throughthe churn body. Fig. 4 is a section on the line 4-4 of Fig. 3illustrating the arrangement of the body and acket outlet cocks.

In the accompanying drawings, the numeral 5 designates a supportingframe including the vertical standards 6, constructed at their upperends as bearings for the trunnions 7 carried by the churn proper, one ofsaid trunnions being extended to receive a detachable crank handle 8employed for rotating the churn. The latter comprises an inner body 9,and an outer body 10 surrounding the body 9 in spaced relation, so thata jacketed. space 11 occurs therebetween.

The bodies 9 and 10, at their lower ends have connection with a commonbottom 12.

Leading from the interior of the body 9 is a pipe 13 which projectsthrough the jacket 11 and the body 10 and carries a turning plug 14, thepipe 13 being employed to drain buttermilk from the body 9. A pipe 15leads from the space 1 1, the pipe 15, having a turning plug 16, andserving to permit of the drainage of water from said space. The body. 9at its upper end is threaded interiorly as at 17 and exteriorly as at18. A cap 19 is employed to close the body 9 and is constructed withexternal threads 20 for engagement with the threads 17. The cap 19likewise has a handle 21 to permit of its convenient manipulation. A cap22 is employed to close the space 11. of substantial ring shape and isconcavo convex in cross section, the inner edge portion of said capbeing formed with threads 23, for engagement with the threads 18. Theouter edge portion of the cap 22 overlies the body 10 and is provided onits inner face with an inset rubber packing gasket 24. The outer face ofthe outer edge portion of the ring 22 is milled as at .25, whereby saidcap may be conveniently removed.

In use, the space 11 is filled with water. In the summer time, the wateris cold to prevent the butter from becoming soft and in winter time, thewateris warm to facilitate the formation of the butter.

The invention is simple in its structural details, inexpensive tomanufacture and practical and efficient in use.

From the foregoing description it will be seen that simple and efficientmeans are provided for accom lishing the objects of the invention, butwhi e the elements herein shown and described are well adapted to servethe functions set forth, it is obvious that various minor changes may bemade in the propor tions, shape and arrangement of the several parts,without departing from the spirit and scope of the invention as definedin the appended claims.

lVhat is claimed is:

A churn comprising a body having spaced inner and outer annular wallsforming an inner milk chamber and an outer water cham ber, a disk platesecured to the lower extremities of the walls to form an end closure forthe chambers, said inner wall having threads on its inner and outerfaces at the opposite open end of the inner chamber, a removable caphaving exterior threads engaging the threads in the inner face of saidinner wall, and a removable annular ring member forming a cap ofinverted U-shape in cross The cap 22 is section, and in threadedengagement With In testimony whereof, I affix my signature, the threadson the outer face of the inner wall in presence of two Witnesses. andoverhanging the upper edge of the outer Wall to close the Water chamber,said ring JENNIE MOIR' 5 member adapted to surround the first lnen-Witnesses:

tioned cap whereby the latter can be re A. J. HILTON,
